Looks like I'll be taking at least 3 of these. They are a mystery to me since they are different from other credit-by-exam programs. Any experiences? Are they full of trick questions or are they more straight forward? How would you rate their difficulty in comparison to other exams? How are they scored/graded? How long does it take for them to be scored? Whatever info you can give me would be much appreciated!

Exams I will likely take: Business Policy; Advertising ; Marketing Communications
